Synopsis

Input Parameters

- the indices into j for the start of each local row (starts with zero)

j

- the column indices for each local row (starts with zero) these must be sorted for each row

v

- optional values in the matrix

Notes

The order of the entries in values is specified by the MatOption MAT_ROW_ORIENTED. For example, C programs
may want to use the default MAT_ROW_ORIENTED=PETSC_TRUE and use an array v[nnz][bs][bs] where the second index is
over rows within a block and the last index is over columns within a block row. Fortran programs will likely set
MAT_ROW_ORIENTED=PETSC_FALSE and use a Fortran array v(bs,bs,nnz) in which the first index is over rows within a
block column and the second index is over columns within a block.
